    f(3)=(3*3+1)/(3+4i)=10(3-4i)/25=6/5+4i/25

    was it f(2+i) or f(2+1) = f(3)?

    \[f(2+i)=\frac{3(2+i)+1}{2+i+4i}\] what exactly do you want? you seem to be in upper level class so what should i write this as or i mean what is the goal

    you are on the right path alexis, you just need to get the complex number out of the denominator of that fraction.

    Alexis please review the multiplication of the denominator: (2+5i)(2-5i). It is not:\[4-5i ^{2}\]
